This invention relates to window guards.

An object of this invention is to provide an extensible window guard which may be adjusted to fit a relatively large range of window widths,

and locked in adjusted position.

A further object of this invention is to provide a strong and rugged jimmyproof window guard of the character described, which shall be relatively inexpensive to manufacture, light in weight, easy to manipulate and withal, practical and efiicient to a high degree.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the fea- 5 tures of construction, combinations of elements,

and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which are shown one of the Various possible illustrative embodiments of this invention.

Fig. 9 is a cross-sectional View taken on line 9-9 of Fig. 6; and

Fig. 10 is a cross-sectional view taken on line ifi-lt of Fig. 6. 45 Referring now in detail to the drawings, 10 designates a window frame having side portions H formed with pairs of grooves 12 and I3 in which are slidably mounted the window sashes i4 and I5 respectively. Within the groovesl3, 50 between the furring strips l6 and below the sash I5 is a window guard l'l embodying the invention.

The window guard I1 is extensible, and comprised generally of a pair of slidably connected 55 members 18 and I9, mechanism 20 to fix said members against relative movement and key actuated, releasable locking means 2| to retain said mechanism in fixed position.

Member I3 comprises a pair of vertical flat bars 23, 24 resting on the bottom portion Illa 5 of frame Ill. Bar 23 is disposed in groove l3 at one side of the window frame. Said bar 23 is of such height as to substantially reach the underside of upper sash l5. Fixed to and between said bars 23, 24 are a plurality of spaced, parallel, 10 horizontal, similar grates 25 of channel shaped transverse cross section. The grates 25 have downwardly extending side flanges 26, the ends whereof pass through openings in bars 23, 24 and are headed, as at 21, to rivet said grates to said bars. Bar 24 is formed with rectangular openings 28 just below each grate 25, for the purpose hereinafter appearing. Bar 24 may be shorter than bar 23, as shown in the drawings. Although six grates 25 are shown in the drawings, it willbe understood that any suitable number of grates may be employed.

Member l9 comprises a pair of vertical fiat bars 30 and 3| interconnected by parallel, horizontal spaced grates 32 of channel shaped transverse cross section. The bar is similar to bar 23 and is received in groove I3 at the other frame portion II and between the furring strips I 6. Bar .3! does not extend to the bottom Illa of the frame, as illustrated in Fig. 1 of the draw- 30 ings. There are as many grates 32 as grates 25, the former passing through openings 28 in bar 24. Bar 3| is formed with a rectangular opening 34 above each grate 32, through which passes one of the grates 25. 35

It will now be understood that the members l8. l9 are relatively movable, one guiding the other, to extend or shorten the width of the window guard to fit various sized windows.

A pair of said grates 32 (second and fifth from top and designated by numeral 32a) are formed with a plurality of closely spaced aligned openings 40 in the top walls of said grates. The length of grates formed with said openings determines the amount of adjustment that can be made. For example, if there are twelve inches of openings 40, the window guard can be widened twelve inches.

The mechanism 20 for retaining the members l8 and [9 in relatively fixed position comprises a pair of parallel, elongated, similar, symmetrically disposed channel shaped members 42 having inwardly extending flanges 43. The members 42 are spaced apart and disposed at opposite sides of the grates 32, 32a, and adajacent the bar 24. The channel shaped members 42 are fixed to one another by rivets 46 and 41, carrying spacing sleeves 46a and 41a disposed between said members. The rivet 46 is located above the third grate 32, whereas, the rivet 41 is located below the fourth grate 3211. As will appear hereinafter, said rivets limit reciprocation of 'the mechanism 20. When mechanism 23 is moved upwardly, the sleeve 41a on rivet M .will contact the under edges of one grate 32 to limit upward movement, and when said mechanism is moved downwardly, the spacing sleeve 46a, on the rivet 46, will contact another grate 32 to limit downward movement.

The mechanism 28 is connected to the bar 24 for sliding movement thereon, by means of a pair of spaced, vertical plates 48, fixed to the bar 24 in spaced relation thereto, by rivets G9. The plates 48 are substantially square in shape and disposed between the channel shaped members 42, and engage the inner surfaces of adjacent flanges 43, 'of the channel shaped members 42.

Fixed to and between the members 42, are a pairof spaced, horizontal plates 52, each carrying an upwardly extending pointed element or pin 53 adapted to-be received within the openings 40'in the grates 32a. The plates 52 are disposed below the grates 32a. When the mechanism 20 is in releasing'position, as shown in Fig.6 of the drawings, the pointed elements 53 are disposed belowthe grates 32a. In such position, the members l8 and I9 may be slidably moved one relative to the other to widen or narrow the window guard. Upon moving the mechanism 20 upwardly however, the elements 53 engage within aligned openings .48 to prevent such relative movement between the members l8 and 9 The locking means 2| for holding the mechanism 20 in its up position, as shown in Fig. 3 of. the drawings, comprises a channel shaped member 60 having parallel flanges 6|, adapted to receive a portion of the mechanism 28 therebetween, and formed with extending apertured ears 62, receiving theends of a transverse, horizontal pivot pin 64, which serves to pivotally attach said member 60 to said mechanism. The lower end of member 60 is formed with a slot or notch 65, and riveted to the inner surface of said, member, transverse of said slot, is a strip 66. carrying a roller 61. The pivot pin 64 is so located, and the member 60 is of such length, that when the mechanism 20 is in down or releasing position, the roller 61 will contact one of the grates 32, to maintain said member in inclined position, with the lower end of said member spaced from said mechanism; and when said mechanism is up or looking position, said member will be in vertical position with the roller still in engagement with said grate.

On member 60 is a key cylinder 68, carrying a latch 69, disposed between the flanges 6!. The latch 69 is narrower than the space between the inner edges of the'flanges 43, whereby said latch may move through said space when mechanism 2!) is moved upwardly. When said mechanism 20 is in its up position, turning of the cylinder 68 by a key, through an angle of 90, will cause the latch to engage the flanges 4.3 of the channel shaped members 5-2 to lock the member 60 in vertical position, as shown in Figs. 3 and 4 of the drawings.

It willnow be understood that to lock the window guard, it is merelynecessary to raise the mechanism 20 causing the locking means 2| to swing to vertical position, and the elements 53 to engage within a pair of aligned openings 40. The roller 6'! serves to prevent rubbing off of the paint on the portion of the grate 32 it contacts.

The lower rivet 41 aids in rendering the window guard jimmyproof. When the member 2| is swung to vertical position, the key is inserted into the cylinder 63 and given a quarter of a turn to bring the latch 69 in engagement with the flanges 43. The key may then be removed and the window guard is then looked in place on the window within the grooves |3 of the window frame, and cannot be removed.

When it is desired to remove the window guard from the window frame, the key is again inserted in the cylinder 68 and given a quarter of a turn in the opposite direction to bring the latch 69 to vertical position. The member 2| may then be swung outwardly, to the position shown in Fig. 6, the mechanism 243 being lowered to disengage the pointed elements 53 from openings 43. The members. l8 and I9 may then be moved together, and the window guard removed from the window frame. Although the window guard is shown in the drawings to have six grates, two of which are formed with openings to receive two pointed elements, it will be understood that the number of grates, the number of grates with the openings, and the number of pointed elements may be varied to suit.

When the window guard is used with casement windows, the bars 23 and 33 may be provided with outwardly extending pins and the window frame formed with sockets to receive said pins.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
